How to Change the Admin Password in Magento?

For changing the administrator password you should:

1. Log in to your Magento admin panel
2. Select the “System” tab
3. click the “My Account” menu item
4. Here you can see the fields where you can enter your admin password

In case you are not able to log in to your Magento admin panel at all, the admin password can be changed in the database directly.

1. Open your database with the “phpMyAdmin” tool or any other database management tool. And open the “admin_user” table
2. Click the edit icon
3. With that done, type your new password in the value field
4. Note that in the function drop-down menu you should select “MD5″
5. Save the changes
